Legend:
"null basebar of A-frame" has no material present for the basebar while there are still side members.
A-frame with near parallel sides has a virtual triangle that is represented, even in the case of absolute parallelism (almost impossible to actually materialize) where the virtual apex is very high or perhaps even at the infinite point zenith.

Will the A-frame of Pilcher (where the basebar becomes a null basebar made possible by a high-hat compression member and high-hat lines tensionally closing two kingposts against the compression member) be one tactic for wing running (WR) and hang gliding?
Most of us know our basebars of our A-frame as a solid bar that is in tension during positive-loaded flight (and thus sometimes with a safety backup buried cable inside the basebar ready to take tension if the basebar becomes broken in any manner that would not let tension be held). A number of ways of construction provide a null basebar (no material present in the A-frame where popularly we find the basebar). One method is sturdy downtubes from a frame in the wing; another is rigid lateral flying struts. Another is that which is found in Pilcher's hang glider of old.
Why? The open space leave full room for running. Woopy pilots have the two sides and the null basebar. A very neat rigid wing hang glider had two parallel (nearly) A-frame control side tubes and the null basetube.

Thanks, Tony C,

ePF ... electric personal flight; but with recharge from use of kite energy, wind-turbine, pilot-muscle input, solar energy, and regenerative energy when soaring lift is great and abundant.

Site appearance is inviting and pleasant.

I sent reference of your doing to Dean Sigler who has had particular interest in small multiple motors for ePF.

A pet first goal of mine is eHG: Limit the AGL to 30 m and hone the e-system just to be not more than needed to attain a climb out of the 30 m off level land. Use fast running and then turn on the props for a climb; then have not much energy left at 30 m for a practice glide and practice running landing. The scenario would not be just for training, but for fun, physical fitness. Ultimate dream is to have the frame of the wing BE AN ULTRACAPACITOR itself for such purpose. Then upon landing, tap stored charge source for a recharge of the ultracap wing frame. Then run like mad, trigger e-driven props and climb again to 30 m for a short glide and running landing. The system would be equipped with "Safe-Splat" mitigation to care for any stumbling that may occur at take-off run or running landing. Focus is on the running...

Be well,

By the way, your wing running concept might benefit from a "Wing Running Meet" to bring people together for an event.

Otto Lilienthal's birthday is coming up again ... what do you think?

On wing running
From all past observed accidents, I'm convinced that wing running without safe-splat (safe after stumbling, etc.) can be extremely damaging to people. Broken hands, necks, arms ... Ouch! Upon trip or stumble, I am aiming for sliding, rolling ... while body is held by tension and also limited from forward swinging. Rapid stopping is part of the huge challenge. Gouging of small wheels is a challenge.
What could be interesting in wing running on level ground? Safety at stumble could be interesting. Then sprints could remain safe. Pitch-down of wing rapidly in sprint is challenging; in such instance, one would want safe results. Races then could be interesting.
On level ground: Injury loses. Long jumps with wing assistance might be interesting. Take-off line defined and then see where splat occurs without injury; measure the distance. Or run and have time in air (without thermal) in relatively calm wind.
Endurance? Distance wing running?

What would amount to a wing runner's "wing" ? Would there be a minimum area relative to empty weight?

There are wing runners using canopy wings kited ... to give resistance training to muscles in preparation to run conventional track and field events.
Flying over a set high jump bar? Wing run and then clear the bar or elastic string?

My gut feel is that we need to prove some Safe-Splat designs that show well safety upon stumbles in sprints. I would like to get logged 1000 wing runs with lots of stumbles ... and no tissue tears.

I am rusty on how to have "organized assemblies" without the organizing agent taking on liabilities.

And I do not want to be prohibited from parks. Organized assemblies are far different from spontaneous individual recreation activities. I do not want to see signs posted on public parks: "No wing running allowed." People running in parks already are actually carrying tiny wings (their hats, their shirts, etc. are tiny wings).

Informal social exchanges like: "Some guys and gals will be wing running at _________________ on __________________" will end up having more than one wing-runner sometimes.

Training muscles and nerves for wing running takes time. Progressing toward sprint speed and good endurance without obtaining physical injury will take time. With Joy Frame, one may start with small wings and work up to larger wings.

When strength, speed, and endurance is obtained, one may look to some shallow inclined streets or soil places. Judging winds and effect of incline will be added parameters. Ground-skim with Safe-Splat Joy Frame will result in longer ground-effect skimming glides. Pitch should be mastered; one will not want to flip over backwards, etc. Again, large training cycles would be a possible chosen goal. Health and Fitness. No tissue tearing.

When wing running is shown to be fun and safe, I trust that someone will move things to organized meets. I will stay developing the Safe-Splat part of wing running. And if some future meet requires me to have insurance, then I would not attend. I do not carry insurance to run and walk in the park while I run with wings now; this will be continued for me. Others might get involved in insurance, etc.

Otto L. had a strong "jump" text.
The wing-running tradition without Safe-Splat has been a long-term discouraging tissue-tear "crashery". Differently, the positive Safe-Splat era will see high-energy wing running for itself as well for ground-effect flying and hang gliding. There will be special calm-air adventures with wing when Safe-Splat sprint wing running is well known.
Best,
JoeF

Considerable focus on wing running is embedded in this video:

That video location looked familiar. Then I realized it was my old LZ in Ellenville, NY. The vid was produced by Ryan Voight - a one time friend. It is well done I'd have to say.

The wing runner is running on beach sand. The wing being used is lifting in many directions at once in a near-chaotic manner with a net experience of resistance to the run. One primary use of the shown system is to give the runner high exercise. There is very little potential of gliding much unless the runner ran over a berm; the shown wing would not give a noticed glide angle. In a super wind, the wind could drag the runner and injure the runner's body.

The activity of "parachute running" with very low L/D wings is illustrated some in the following video:



One may also consider using parafoil kites or other kite wings for similar exercise.
The instructor cautions wing runners to warm up the body before doing a launch into speed training.

PGs and kite HGs do wing running often in launching efforts and landing efforts.
Here is a wing running where the wing is an evolute of the Jalbert parafoil wing; the many kite lines are attached to the system's anchor: the PG operator. Exampled is a forward running launch where the kiting occurs.
Disclaimer: This is not a recommendation to do PG over broad spectrum of wind conditions.

When you're watching "Big Blue Sky" keep a sharp eye out for a brief shot of me "wing running" my Skysail on the flat beach at either Torrance or Dockweiler, not sure which. My son Matt called it "comic relief", he thought it was silly. I explained to him that it was a perfectly normal part of learning the technique for ground handling and launch with that very different (at that time) glider. Those other videos shown in this "Wing Running" topic thread back me up. Thanks for this Joe.

I haven't watched the documentary recently so I don't remember if the wing had the original triangle bar or if I had already converted it to parallel bars when that footage was shot. It was much easier to handle and launch with parallel bars.

Wish I had that clip.
